CLASS I. i. 4. 10. OF IRRITATION. 43 



M. M. It mould be d ufted over with very fine powder of 

 gum fandarach, and then replaced. Aftringent fomentations ; 

 as an infufion of oakbark, or a flight iblution of alum. Hori- 

 zontal reft frequently in the day. 



10. Lumbricus. Round worm. The round worm is fuf- 

 petled in children when the belly is tumid, and the countenance 

 bloated and pale, with fwelling of the upper lip. The genera- 

 tion ofthefe worms is promoted by the too dilute (late of the 

 bile, as is evident in the fiukc-worm found in the biliary duels 

 ^nd fubftance of the liver in (heep ; and in water-rats, in the 

 livers of which laft animals they were lately detected in large 

 numbers by Dr. Capelle. Tranfactions of the college at Phila- 

 delphia, v. i. 



Now as the dilute (late of the bile depends on the deficiency 

 of the abforption of its thinner parts, it appears, that the tumid 

 belly, and bloated countenance, and fwelled upper lip, are con- 

 comitant circumflances attending the general inactivity of the 

 abforbent fyftem ; which is therefore to be efteemed the remote 

 caufe of the generation of worms. 



The fimplicity of the ftru&ure of worms probably enables 

 them to exift in more various temperatures of heat ; and their 

 being endued with life prevents them from being deftroyed by 

 digeftion in the ftomach, probably in the fame manner as the 

 powers of life prevent the fermentation and putrefaction of the 

 ftomach itfelf. Hence I conclude, that worms are originally 

 taken into our alimentary canal from without , as I believe finv 

 ilar worms of all kinds are to be found out of the body. 



M. M. The round worm is deftroyed by a cathartic with 

 four or fix grains-of calomel ; and afterwards by giving fix or 

 eight grains of filings of iron twice a day for a fortnight. See 

 Hepatis tumor, Clafs I. 2. 3. 9. As worms are liable t come 

 away in fevers, whether of the hectic or putrid kind, could they 

 be removed by purulent matter, or rotten egg, or putrid flefh, 

 fmce in thofe fevers from the enfeebled action of the inteftines 

 the faeces become highly putrid. 



The (harp fpiculx or hairs, which are found on the pods of 

 cowhage, (truolobium filiqua hirfuta, have been recommended 

 in worm-cafes, and faid to deftroy them by mechanical puncture ; 

 the late Mr. Power of Polefworth, aiTured me, he had had great 

 fu^cefs with this medicine and gave about fix or eight grains in 

 a bolus three or four times on one day, with a brifk cathartic 

 on the next day. Some have recommended chopped hair or 

 bridles for this purpofe. There are numerous (harp fpiculx in 

 the fruit of the wild rofe, which might be worth try ing it this 



difeafe,.
